The Data warehouses and the Average of Averages

Currently working on a project that uses Data entry screens as a Data source for users. The Data will be polled from an Operational Database to the Data warehouse in Quarterly bases and users Enters the values of the KPIs in Quarterly Bases Only

The Problem is if we have a Measure that is calculated using the following Formula (A+B)/C . What Should I store in the Data warehouse is it the Actual Value or the value of each metric alone.

Anyone faced this design before. If yes Any Ideas?
